उत्तर

If 5 is added to three times a number, it becomes the same as 7 is subtracted from four times the same number. This fact can be represented as 5 + 3x = 4x – 7.

Explanation:

Let the number be x.

Now, 5 is added to 3 times the number 5 + 3x.

It is same as 7 is subtracted from 4 times the number, i.e. 4x – 7.

So, the equation formed is 5 + 3x = 4x – 7.
